SV4.5L48 is a 48-inch nominal rigid Secure Vent direct-vent pipe section. The nominal number describes section length, not diameter. The listed system uses a 4-1/2-inch inner and 7-1/2-inch outer pipe.
Installed effective length is 46.5 inches, per the manufacturer’s vent-length table. Calculate the complete route from effective lengths; nominal lengths do not account for engaged joints. The concentric unitized section uses a positive twist-lock connection. Align and fully engage the joint according to the installation instructions before proceeding.
The exact part is listed for Superior DRT2035-E, DRT2040-E and DRT2045-E fireplaces. Other appliances must explicitly list this part or system in their own documentation; appearance or similar dimensions do not establish compatibility. Use only approved system components.
A complete vent system is required for the fireplace, but this individual component and its quantity depend on the selected route. For these fireplaces, horizontal or inclined vent components require 3 inches clearance above and 1 inch at sides and bottom. Follow all applicable vertical-route, termination, wall and roof clearances in the manual. Do not infer that every vent accessory is mandatory for every installation.
